Light, packable and proven, the Atom – an Arc’teryx icon – is a performance warming layer for backcountry adventures, alpine ascents and downtown commutes. Refined for its next generation, we elevated its performance and extended its versatility. The Coreloft™ Compact 60 insulation retains heat when wet and withstands repeated packing and unpacking. The soft, durable Tyono™ 20 face fabric resists wind and weather, and stretch fleece side panels improve ventilation and freedom of movement

*The Atom Jacket was previously the Atom LT Jacket.
